Verdict
The clearest difference is review sentiment: PlugGuard at 100% against ProxiOne's 0%. PlugGuard also leads on update cadence (every 2 days vs every 9 days) and ratings volume (68 vs 2). ProxiOne's advantage is monetization model (free vs freemium) and rating (5.0 vs 4.7). On price, ads, in-app purchases and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PlugGuard sells 1 in-app purchase, starting at $9.99 per year and ProxiOne sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
ProxiOne holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PlugGuard has 68 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of PlugGuard's written reviews are positive against 0% of ProxiOne's, so the app with the better star average is not the one people write more warmly about.
PlugGuard ships an update every 2 days, ProxiOne every 9 days. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
